TRUSS-COUPLING.

Specification of Letters latent.

l'atented Dec. 2S, 119115.

fo @ZZ 'uf/0m "it may Concern.' Y l it known that l, Renner O. Kinopa citizen of Canada, residing at Buffalo, in the county ot' Erie and State of New York, have invented new and usetul improvements in rlruss-Couplings, of which the ollowing is a specification.

This invention relates to trussing which is more particularly designed for use on the roofs oit green houses but which may also he used on the roofs et' other buildings.

rllhe purpose of this invention is to provide simple, inexpensive andv effective tixtures Vfor use in trusses for roofs which permit otheing quickly and properly erected, which will permit the struts to swing freely and adapt themselves tothe strains of the guys and tie rods and thus avoid breakage, and which permit ot readily assembling the parts and retaining tliein in a position 1n which they are alined and present a regular appearance. Y

ln the accompanying drawings Figure is a fragmentary vertical transverse section of the roof of a green house equipped with my improved root trussing nature-s or tittings. Fig. 2 is a perspective view of one of the clips oit the coupling connecting the upper end or the main strut with the rafter and upper and lower guys. Fig. 3 is a v ertical section, on an enlarged scale5 in line 3--8, Fig. l, showing the means for coupling or connecting the upper end of the main strut with the reiter and the adjacent guys. TEig. el is a horizontal section of the sainel in line el-4C, Fig. l. A

Similar letters of reference indicate corresponding parts throughout the several views.

That part of the green house shown in the drawings for illustrating my improved trussing comprises a post l, an elevated ridge 2, an inclined ratter 3 preferably of tubular form connected at its upper and lower ends by upper and lower fittings 4, 5 with the ridge and post, respectively, an inclined brace connecting the post Vand rafter, a gutter 6 arranged at the upper end of the post, purlins`7 arranged on the rafter, a sash bar 8 arranged on the purlins and eX- tending from the ridge to the gutter, clips 9 connecting the rafter, purlins and sash bars, and glass panes 10 mounted on the sash bars.

rllhe trussing for each rafter with which my improvements are associated comprise a inain strut ll arranged below the central part of the rafter, a pair of lower truss rods l2, l2, arranged lengthwise on opposite sides or" the brace 50 and connected at their outer ends with the outer or lowerrafter fitting 5 while their inner ends are operatirelyconnected with the lower end of the main strut, a lower intermediate strut 13 arranged between the Vlower truss rod and the i'at'ter, an upper sectional truss rod 14, l5 connected at its outer end with the lower end et the main strut while its inner end is connected with the upper ratter iitting il, an

upper intermediate strut 1S arranged between the upper truss rod andthe rafter, a main tie rod 19 connected at one end with the lower end oi"- the main central strut and with the truss rods, a wind tie rod 20 connected at one end with the lower end of the upper intermediate strut and the upper truss rod a lower guy rod 16 extending trein the lower end et the lower intermediate strut and lower truss rod to the upper end of the main strut, and an upper sectional guy rod 17 extending from the upper end of the main strut to the lower end of the upper intermediate strut and upper truss rod, as shown in Figs. l and 2.

rlhe coupling for connecting the upper end of the main strut, rafter and guy rods is constructed as follows: 53 represents two clips each of which is provided at its upper end with al curved jaw 54 adapted to engage with one side of the rafter and at its lower end with a transverse opening 55 and a laterally projecting perforated ear 56. On its inner-iside and concentrically around the opening 55 the clip is provided with a circular collar 57 and between the opening 55 and the jaw of this clip the saine is provided vith an intermediate opening 58. The two clips 53 are placed with their jaws in engagement with opposite sides of the rafter and their collars in engagement with each other and the same are held in this position by means of a main transverse cou pling bolt 59 passing through the lower openings 55 and an intermediate coupling bolt 60 passing transversely through the intermediate openings 5S. The upper end of the inain strut is arranged between the lower ends or.' the clips 53 and an opening (il in its upper end receives the collars 57 of these clips. The latter are preferably made by casting the saine in molds made by the same pattern but when the two clips are secured to each other with the faces of theirj aws and theends of their collars opposing each other the ear 56 of the same project laterally in opposite directions. One oit' the ears 56 receives the shank 62 which is bent laterally in one direction on one of the z@guy rods and secured therein by a screw nut 63 bearing against the outer side of said ear while the other ear receives a shank 64: bentv laterally on the end of the other guy rod and secured therein by a screw nut 65 bearing against the outer side of the last mentioned ear, as shown in Fig. 4. This connection between the main strut and the rafter and guy rods permits the strut Vto swing and turn under the strains to which it is subjected without liability of breakage and still maintain a .Copies of this patent may be obtained for firm and reliable connection between the parts with which the strut is associated.

I claim as my invention: v

A truss coupling comprising two clips each of which is provided at its upper end with a jaw and at its lower end .with an Y opening, a collar around said opening and a laterally projecting ear, said clips engaging their jaws with opposite sides of amain Y i truss member, supportingan auxiliary truss Y ve cents each, by addressing the 'f Goimiiissonerl of Patents.
